This wide-bore solid state NMR instrument is equipped with a 395 GHz Gyrotron for Dynamic Nuclear Polarization (DNP). This instrument is capable of utilizing DNP of solid samples doped with compounds containing electron radicals, typically enhancing the NMR spectral sensitivity by 10 to 100 fold. The system is equipped with several DNP and room-temperature probes for studying biological solids, powders, and micro-crystalline samples including:
3.2 mm HCN low-temperature MAS probe for DNP. Experiments are carried out at 100 K for efficient transfer of electron polarization to the nuclear spins of interest, with MAS speeds of up to 17 kHz. The probe is set up for triple resonance proton, carbon, and nitrogen and is ideal for studies of biological solids.
3.2 mm HX low-temperature MAS probe for DNP. Experiments are carried out at 100 K for efficient transfer of electron polarization to the nuclear spins of interest, with MAS speeds of up to 17 kHz. The variable X channel makes it of particular interest for studies of inorganic solids and polymers.
1.9 mm HCN MAS probe, with spinning speeds up to 42 kHz, is capable of averaging out the detrimental dipolar and chemical shielding interactions, thereby dramatically improving sensitivity and resolution of the experiments.
The 7 T gyrotron magnet is cryogen-free, requiring little or no maintenance for microwave generation. The long hold times of liquid helium (over 4 months) and liquid nitrogen (3 weeks) of the 600 MHz Ascend NMR magnet reduces maintenance and down-time of the system.
